d(-)-Lactic Acid Production by Leuconostoc mesenteroides B512 Using Different Carbon and Nitrogen Sources
(Applied Biochemistry and Biotechnology, 2011-08-01) [Artigo]
Sugar concentration from sugarcane juice and yeast autolysate increased lactic acid production more than the other agro-industrial substrates tested. The concentrations of these two components were further optimized using ...
Rhamnolipids and PHAs: Recent reports on Pseudomonas-derived molecules of increasing industrial interest
(Process Biochemistry, 2011-03-01) [Artigo]
Rhamnolipids (RL) and polyhydroxyalkanoates (PHA) from Pseudomonas species show a wide range of potential industrial applications. Rhamnolipids are surface-active molecules that are usually produced by Pseudomonas aeruginosa ...
Lactic acid production by new Lactobacillus plantarum LMISM6 grown in molasses: optimization of medium composition
(Brazilian Journal of Chemical Engineering, 2011-03-01) [Artigo]
A Plackett-Burman experimental design was used to evaluate seven medium components added to molasses (corn steep liquor, sodium acetate, magnesium sulfate, manganese sulfate, ammonium citrate, potassium phosphate and Tween ...
Rhamnolipid emulsifying activity and emulsion stability: pH rules
(Colloids and Surfaces B: Biointerfaces, 2011-07-01) [Artigo]
Rhamnolipids have excellent emulsifying power with a variety of hydrocarbons, aromatic compounds and vegetable oils. This paper evaluates the effect of pH ranging from 3 to 9 on the emulsifying activity and stability of ...
Influence of nitrogen source and sucrose concentration on inulinase production by Kluyveromyces marxianus in fed-batch fermentation
(African Journal of Biotechnology, 2011-09-26) [Artigo]
This work studied the influence of nitrogen source and sucrose concentration in the feeding medium for biomass and inulinase production by Kluyveromyces marxianus var. bulgaricus. The results show that the best nitrogen ...
